VAPOR-LAMP.

Specification of Letters Patent No. 28,924, dated June 26, 1860.

To all whom it 'may concern:

Be it known that I, GEORGE WALKER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Vapor-Lamp; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a side sectional view of a lamp constructed according to my invention. Fig. 2 a detached elevation of the burner, heater and adjoining parts. Fig. 3 a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a lamp for burning volatile hydro. carbons by first Vaporizing or gasifying the same, the illuminating flame being fed by the vapor and the invention being capable of being applied to the ordinary fluid lamps.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, represent a lamp which may be constructed in any of the known forms and provided with a cap B, containing ordinary wick tubes C, C. The above parts being of usual construction do not require a more minute description. The lower part of the lamp A, has a curved tube D, attached, said tube curving upward and having a flanch or cap E, screwed on its upper end as shown plainly in Fig. l. To the lianch or cap E, a wick or packing tube F, is attached centrally and there is also attached to the flanch a cap a tube or cylindrical shell Gr, which has a concentric position with the wick or packing tube F. The wick or packtube F, communicating with the tube D, and the interior of the lamp A, but the flanch or cap E, serves as a bottom for the shell G, as shown in Fig. l. To the upper end of the tube F, a burner I-I, is attached. This burner may be formed like any of the ordinary Vapor or gas burners. I do not confine myself to any particular form of burner.

Between the tube F, and the shell G, there is allowed sufficient space to receive a tube I, which is considerably thicker than either the tube F, or shell G. This tube I, is allowed to slide freely in and out between the tube F, and the shell G, and it has two curved lateral plates c, c, projecting from it at opposite points, both of which are shown in Figs. 2 and 3. The inner parts of the plates c, c, when the tube I, is adjusted in proper position, fit in recesses d, in the upper end of the shell G, to prevent the casual turning of the tube I, when adjusted in proper position. To the upper part of the tube I, there is also attached by a joint e, a heater J, which is of elliptical form and may have an open space f, at its center as shown clearly in Fig. 2. To the lower part of the heater J, below the joint Z, there is attached a button or head g, which serves as a weight and has a tendency to keep the upper part of the heater outward from the burner I-I. The lower part of the heater when the weight g, is attached bears against an eccentric collar K, which is fitted on the upper part of the shell G. The plates c, c, of tube I, when the latter is adjusted to its proper place, have their inner ends in line with the base of the burner H, and the heater J, has its open space 7, about opposite the burner see Fig. 2.

The tube F, is supplied with a suitable packing or wick L, which extends upward to the base of the burner.

The operation is as follows: If an ordinary fluid-burning lamp is required the wicks of the tubes C, C, are lighted, the lamp being filled, trimmed and treated or used in the ordinary way. When a Vapor lamp is required the tube I, is removed from the tube F, and shell G, and heated in a fire and then replaced. The encompassing of the wick or packing tube F, by the heated tube I, soon causes the saturated wick or packing L, to be warmed and the fluid therein vaporized, the vapor being ignited and burning with an illuminating flame from burner H. The heater J, and plates c, c, keep up the temperature of the tube I, the former being heated from the flame and the heater J, may be made to transmit a greater or less degree of heat to the tube I, below, by adjusting the former nearer to or farther from the flame, which may be accomplished by the eccentric collar K, in connection with the weight g. By this adjustment of the heater the height of the illuminating flame and consequently its intensity may be regulated as desired.

The tube I, is made thick in order that it may retain the heat imparted to it and consequently insure an even or constant evaporation of the fluid, not being in consequence of its thickness subjected to sudden changes or fluctuations Which might otherwise occur to a greater or less extent by any disturbing causes in the vicinity of the flame. The shell G, prevents the radiation of heat from the tubes F, I, and renders the burner J, and its tube I, efficient in its operation.

By having the vapor-burning apparatus all placed at the Outer side of the lamp A, the fluid Within the same is kept cool and consequently prevented from gasifying and exploding.

I do not claim the tube I, nor the heater J, separately, but:

Having thus described my invention what GEORGE WALKER.
